Dimenhydrinate dosage
Dramamine Original Formula is over-the-counter, so the Drug Facts DIRECTIONS on the box are exactly what you follow — no guesswork. For adults and children 12 and over, the label says take "1 to 2 tablets every 4-6 hours, do not take more than 8 tablets in 24 hours." Take the first dose "½ to 1 hour before starting activity" to prevent motion sickness. The single most important ceiling: no more than 8 tablets (400 mg) in 24 hours for adults. Before you dose, confirm which Dramamine you have — "Less Drowsy" is meclizine, taken only once a day, so the numbers below do not apply to it.
These are the doses from the FDA Drug Factslabel — what the product itself directs. Follow your specific product’s label, don’t exceed the stated daily limit, and check with a pharmacist if you take other medicines or have a health condition.
Approved for: The Dramamine Original Formula Drug Facts label (dimenhydrinate 50 mg) lists it as an "Antiemetic" used "for prevention and treatment of these symptoms associated with motion sickness: nausea, vomiting, dizziness." It is a motion-sickness drug, not a general nausea or allergy remedy.
Available as: Dramamine Original Formula: dimenhydrinate 50 mg tablets. (Dramamine also sells 25 mg chewable dimenhydrinate tablets and a kids' chewable — check your box's strength. Critically, "Dramamine Less Drowsy" is NOT dimenhydrinate at all — it is meclizine HCl 25 mg, a different drug with different dosing.)
| Use | What the label says |
|---|---|
| Adults and children 12 years and over (Dramamine Original, dimenhydrinate 50 mg) | Label directions: "take 1 to 2 tablets every 4-6 hours, do not take more than 8 tablets in 24 hours." For prevention, "the first dose should be taken ½ to 1 hour before starting activity." |
| Children 6 to under 12 years | Label directions: "give ½ to 1 tablet every 6-8 hours, do not give more than 3 tablets in 24 hours." First dose ½ to 1 hour before activity. |
| Children 2 to under 6 years | Label directions: "give ½ tablet every 6-8 hours, do not give more than 1 ½ tablets in 24 hours." This is the smallest dose on the label. |
| Children under 2 years | Do not give. The label warning reads: do not give to "children under 2 years of age unless directed by a doctor." For any young child, use weight-based dosing under a clinician's direction rather than an adult tablet. |
| "Dramamine Less Drowsy" — a DIFFERENT drug (meclizine HCl 25 mg) | This is not dimenhydrinate. Its own Drug Facts label directs adults and children 12+: "1 to 2 tablets once daily, or as directed by a doctor," first dose ½ to 1 hour before activity, and "do not give to children under 12 years of age unless directed by a doctor." Once daily — do NOT re-dose it every 4-6 hours like the Original. |
Maximum dose
Dramamine Original (dimenhydrinate 50 mg), OTC 24-hour ceilings, quoted from the label: adults and children 12+ — "do not take more than 8 tablets in 24 hours" (8 × 50 mg = 400 mg); children 6 to under 12 — "do not give more than 3 tablets in 24 hours"; children 2 to under 6 — "do not give more than 1 ½ tablets in 24 hours." "Dramamine Less Drowsy" is a separate drug (meclizine 25 mg) with its own ceiling: "1 to 2 tablets once daily" — not the dimenhydrinate numbers above.
Dose adjustments
Age floors (from the label): do not give dimenhydrinate to "children under 2 years of age unless directed by a doctor"; "Dramamine Less Drowsy" (meclizine) says "do not give to children under 12 years of age unless directed by a doctor." "Ask a doctor before use if you have a breathing problem such as emphysema or chronic bronchitis, glaucoma, [or] trouble urinating due to an enlarged prostate." Pregnant or breast-feeding: "ask a doctor before use." Ask a doctor or pharmacist before use if you are "taking sedatives or tranquilizers." Older adults are more sensitive to the anticholinergic and sedating effects — start with 1 tablet.
Dosing safety — read before you rely on any number
Dimenhydrinate is strongly sedating: "marked drowsiness may occur." The label says to "avoid alcoholic drinks," warns that "alcohol, sedatives, and tranquilizers may increase drowsiness [and dizziness]," and to "be careful when driving a motor vehicle or operating machinery" — do not drive until you know how it affects you. It is anticholinergic, so it can worsen glaucoma, enlarged-prostate urinary trouble, and breathing conditions (ask a doctor first). Do not stack it with other antihistamines or sleep aids — combining anticholinergic/sedating drugs multiplies the effect. In case of overdose, get medical help or contact a Poison Control Center (1-800-222-1222) immediately.
Bottom line
For Dramamine Original (dimenhydrinate 50 mg): adults and children 12+ take 1 to 2 tablets every 4 to 6 hours, no more than 8 tablets (400 mg) in 24 hours; take the first dose ½ to 1 hour before you travel. Ages 6 to under 12: ½ to 1 tablet every 6-8 hours, max 3/day. Ages 2 to under 6: ½ tablet every 6-8 hours, max 1½/day. Under 2: only if a doctor directs. It causes marked drowsiness — don't drive or drink alcohol. Before dosing, confirm your box says "dimenhydrinate," because "Dramamine Less Drowsy" is meclizine 25 mg taken just once a day.
Frequently asked questions
How much Dramamine can I take?
For Dramamine Original Formula (dimenhydrinate 50 mg), the label directs adults and children 12 and over to take "1 to 2 tablets" per dose, and "do not take more than 8 tablets in 24 hours" — that is a maximum of 400 mg a day. Take the first dose ½ to 1 hour before activity.
How often can you take Dramamine?
Adults and children 12+ can take a dose "every 4-6 hours" per the dimenhydrinate 50 mg label, up to 8 tablets in 24 hours. Children 6 to under 12 dose "every 6-8 hours" (max 3 tablets/day); children 2 to under 6 dose "every 6-8 hours" (max 1 ½ tablets/day).
Is "Dramamine Less Drowsy" the same dosing?
No — it is a completely different drug. "Dramamine Less Drowsy" is meclizine HCl 25 mg, not dimenhydrinate, and its label says adults and children 12+ take "1 to 2 tablets once daily." Do not dose it every 4-6 hours. Always check which box you have before taking it.
Can I give Dramamine to my child?
The dimenhydrinate label allows ages 6 to under 12 (½ to 1 tablet every 6-8 hours, max 3/day) and ages 2 to under 6 (½ tablet every 6-8 hours, max 1 ½/day). For "children under 2 years of age," do not give it "unless directed by a doctor," and use weight-based dosing from a clinician for young children rather than an adult tablet.
How soon before traveling should I take Dramamine?
For motion sickness, the label says "the first dose should be taken ½ to 1 hour before starting activity" — so take it roughly 30 to 60 minutes before you get in the car, boat, or plane, not after nausea starts.
Can I take Dramamine with other allergy or sleep medicines?
Be careful — dimenhydrinate is itself a sedating antihistamine, so combining it with other antihistamines (like Benadryl/diphenhydramine) or nighttime sleep aids stacks the sedation and anticholinergic effects. The label also says to avoid alcohol and to ask a doctor or pharmacist first if you take sedatives or tranquilizers. Check every product's active ingredient to avoid doubling up.
Will Dramamine make me drowsy?
Yes. The label states "marked drowsiness may occur" and warns to "be careful when driving a motor vehicle or operating machinery" and to avoid alcohol. Do not drive until you know how it affects you. If you need a non-drowsy option, that is the separate meclizine "Less Drowsy" product.
